More recently the DPRK celebrated its recent intercontinental ballistic missile test with another series of stamps.

The set contains several stamps showing the missile preparing to be fired and soaring into the sky, as well as two more showing leader Kim Jong-un signing the launch order, and celebrating after.

In a statement published by the state-run news agency KCNA, officials said: “All those stamps represent the success in the test-fire of ICBM Hwasong-14, a breakthrough into the final stage of rounding off the national nuclear force.

“It is a great victory won by North Korea in the anti-imperialist, anti-US showdown.”
